8 way splitter for GPS to kiwi's and GPSDO needed
Hi,
Can anyone recommend a 8way splitter to connect my kiwis and a GPSDO for my lab.
What technology I need to look for, to pass DC to the outside antenna but don't (DC-)connect all Kiwis together...

Re: What happens with old spots not yet uploaded (probably because of Internet failure) but stored in txt files...
The wsprnet upload API is not well documented and so I had to experiment with its usage and failure modes.
I found that some batch uploads are accepted by wsprnet, but in its status response wsprnet

I too had seen this in the past where wsprdaemon buffered over 3000 spots while my internet was down for several hours, and when the internet connection restored, after ~15 minutes, WSPRNET accepted

Yes, I think the WD upload service only looks for spot files in receivers which are currently scheduled to be running. That does seem to be a potential source of late uploaded spots, although spots

Dear,
During last night I probably had an Internet connection failuer, so from 20h utc yesterday until 4h utc in the morning, there was nothing uploaded.
The wsprdaemon script created a lot of txt

I mean the current one, which wsprdaemon is using. However I remember the last update of wsprd decoder engine, it was said by the developers, that it should be more efficient in busy bands. Also the

Re: first time more than 3000spots/hour on all bands...
Jim,
on 20m (and the higher bands) usually I hear the locals (100km distance) best, when both antennas are in the same direction (back-scatter)
So in the evening in 20m CW or SSB if stations put their

Re: first time more than 3000spots/hour on all bands...
yes, you can filter.... Phil's website (VK7JJ) offers the possibility.
Obviously, due to the short skip "QRM" the reception capability for the much weaker DX stations is limited. When there is so much

Re: KFS reception quality - IMD and other (internal?) noise sources...
I have just returned from 5 hours at KFS and have time for only a brief report:
1) I removed the Nooelec AMB BF and 6/9 dB pads which were between the Qbit LNA outputs and the Kiwi RF inputs.

Re: WSPRDaemon creating empty spot files and nothing for WSPRNet
Duncan gave me ssh access to his Pi and I was able to see that his RaspSDR wasn't sending audio through the kiwirecorder session, nor was autowspr able to decode on the RaspSDR. Duncan later reported

Perhaps there is way to filter out by distance and disregard spots that are under xxx Km?

Re: first time more than 3000spots/hour on all bands...
Looking at the data, I see that the EU advantage over North America is on 17-10m While I'm sure that much of that is from E and F skip I'd bet there is some GW and Ground Scatter in there

We US stations might as well pack up our tents and go home:) As soon as the cycle moves along we will be lucky to make the top ten World Wide.

Re: first time more than 3000spots/hour on all bands...
just checked: 20m only spots frequently about 40stations per 2min... currently at 900spots/hour - incredible and only possible with the current decoder, I guess - I don't think earlier versions were

Re: KFS reception quality - IMD and other (internal?) noise sources...
In the meantime, I must correct my report from above. There are indeed also during the night severe man-made noise sources, which I believe are produced somewhere in the signal distribution
